Assessment of Federal and Non-Federal Land Mobile Radio Frequency Assignment Methodologies

Bernard Joiner, Alakananda Paul, Kim Cai, and Edward F. Drocella Jr.

Abstract: This report describes how the current frequency assignment process influences spectrum efficiency in the federal land mobile radio frequency bands. In light of the increasing demands for land mobile radio communications, federal spectrum managers must use frequency assignment methods that accurately represent interference to and from systems in the environment to ensure that spectrum is used efficiently. The results of this report will be used to support the implementation of an interference-based frequency assignment process that will improve spectrum efficiency. Standardizing the interference analysis methodologies used in identifying interference-free frequencies in the land mobile radio bands will also improve the overall effectiveness of the federal agencies in performing their missions. This report is one of a series of studies being performed by the National Telecommunications and Information Administration to develop techniques for evaluating and improving the efficiency and effectiveness of federal spectrum use in response to the President’s Spectrum Policy Initiative. The results of these studies will be considered as a whole in setting future policies to improve federal spectrum efficiency.
